GHK-Cu: Copper Binding, Collagen Research and Wound Models
GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine. It is studied in extracellular-matrix, cell-migration and tissue-remodelling systems.Biological context and mechanismThe histidine-containing tripeptide binds copper, an ion used by enzymes involved in matrix maturation and antioxidant…
